Buonconsiglio Castle was originated from a fortified building was erected in the 13th century next to the city's walls. This first building was called Castelvecchio ('Old Castle'), and was the seat of the Bishopric of Trent from the 13th century onwards to the end of the 18th century. The castle is composed of a series of buildings of different eras, enclosed by a circle of walls in a slightly elevated position above the town.
The Castelvecchio is the oldest and most dominant building of the entire housing development. The Magno Palazzo is the 16th expansion in the forms of the Italian Renaissance, wanted by the Prince Bishop and Cardinal Bernardo Clesio (1485-1539), the third part, in the southern end of the complex is the known Eagle tower, which preserves the famous Cycle of the Months, one of the most fascinating pictorial cycles of profane the late Middle Ages.
Bishop George of Liechtenstein was the first to enlarge the castle, in the late 14th century, turning it into a well-styled residence. The Castelvecchio was further modified by Johannes Hinderbach, who had the double loggiato and the Gothic entrance gate built. In the first decades of the 16th century, Bishop Bernardo Clesio had a new residence, called Palazzo Magno ('Grand Palace') built in Renaissance style alongside the old castle. The last great addition was the so-called Giunta Albertiana, from the name of Bishop Francesco Alberti Poja (1686), with which the Castelvecchio and the Palazzo Magno were united.
The castle remained the seat of the Prince-Bishops until 1803. Used by the Austrians as military barracks and, later, as a jail, it decayed. In the 1920s, when Trento was returned to Italy, it became seat of a National Museum and was restored. Since 1992 it is home to the Provincial Gallery of Art.
According to legend, it was connected by a secret tunnel to the city's cathedral, which allowed the prince-bishops to move unseen between them.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
